Hi...this is the second 56k internal modem that i failed to installed on my linux and I need your help to guide me through.
I am using Red hat linux 9 and kernel 2.4.20-8

I use pctel-0.9.6 from linmodem and pct789 as the chipset.
I have completed the installation up to make install and so far it is ok.
when it comes to insmod pctel, there is an incompatible GCC, so I changed to : insmod -f pctel. so far it is ok.
but when it comes to : insmod -f ptserial, here is the error:

using /lib/module/2.4.20-8/misc/ptserial.o
warning: loading /lib/modules/2.4.20-8/misc/ptserial.o will taint the kernel: non-GPL license - GPL linked iwth proprietary libraries.
see: http://www.tux.org/lkml/#export-tainted for information about tainted modules.
warning: loading /lib/modules/2.4.20-8/misc/ptserial.o will taint the kernel: forced load
/lib/modules/2.4.20-8/misc/ptserial.o:init_module:input/output error
Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters.
you may find more information in syslog or the output from dmesg.

So, What should I do now? How can I check the IRQ or where to find the syslog or dmesg file?

Thankss...
